It will take 51 months.

Explanation:

As we know the constant payment of $290 monthly is the annuity payment to pay $12,000 with interest rate of 0.84% per month. The Number of Months can be calculated by following formula.

Loan amount = PV = $12,000

Rate of interest = r = 0.84 %

Monthly Payment = P = $290

PV of annuity = P x [ (1 - (1 + r) ^-n) / r ]

$12,000 = $290 x [ (1 - (1 + 0.84%) ^-n / 0.84% ]

$12000 x 0.84% / $290 = 1 - (1 + 0.84%) ^-n

0.347586 = 1 - (1 + 0.84%) ^-n

0.347586 - 1 = - (1 + 0.84%) ^-n

-0.652414 = - (1 + 0.84%) ^-n

1 / 0.652414 = 1.0084^n

1.532769 = 1.0084^n

Log 1.532769 = n x log 1.0084

n = Log 1.532769 / log 1.0084

n = 51
